Vitamin D deficiency in pregnancy is common, and is linked to increased risk of adverse outcomes including preterm birth, preeclampsia, infection, gestational diabetes and asthma. Vitamin D possesses well-recognized immunomodulatory functions, and programming of the immune system during foetal development can influence asthma-related risk factors and health outcomes in later life. We hypothesized that influencing vitamin D status during pregnancy would impact the immune profil...

In order to examine metabolic and biophysical parameters arising from obesity, male rats were given to drinking 30% sucrose (p/v) for 8 weeks. During the experimental period, animals in the control group (C) consumed higher amounts of food and water, but the body mass was smaller than the group receiving sucrose (S). In this group, the caloric load given to the animals for eight weeks resulted in increased energy consumption, in glycemia and in plasma leptin and abdominal fat....

Objective: The main aim was to evaluate associations between muscular fitness indices and bone outcomes, including hip geometry estimates in young males.Methods: One hundred twenty one males (13.1±0.1 years) were included: 41 swimmers, 37 footballers, 29 cyclists and 14 non-athletes. Lean mass, areal bone mineral density (aBMD) and hip structural estimates were measured using dual-energy X-ray absorptiometry. Relationships of physical fitness tests ...

Objective: The main aim was to evaluate associations between cardiorespiratory fitness and bone outcomes, including hip geometry estimates in young males.Methods: One hundred twenty one males (13.1±0.1 years) were included: 41 swimmers, 37 footballers, 29 cyclists and 14 non-athletes. Lean mass, areal bone mineral density (aBMD) and hip structural estimates were measured using dual-energy X-ray absorptiometry. Relationships of physical fitness test ...

Objectives: Soft tissues, such as fat mass (FM) and lean mass (LM), play an important role in bone development but this is poorly understood in highly active youths. The objective of this study was to determine whether FM or LM is a stronger predictor of areal bone mineral density (aBMD) and hip geometry estimates in a group of physically active boys after adjusting for height, chronological age, moderate-to-vigorous physical activity (MVPA), FM, and LM....

Introduction: Paget’s bone disease (PBD) is the second most prevalent metabolic bone disease. Most patients present with pain or fracture but many remain asymptomatic. Evidence suggests a significant reduction both in its prevalence and clinical severity. Recent papers described differences in clinical course and therapeutic options in the last 10–15 years.Objective: To characterize PBD differences between patients having been diagnosed before ...

Objectives: Cross-sectional studies show that exercise may have positive effects on bone outcomes in youth. However, there is no evidence from longitudinal studies, which type of sports can induce improvements in bone acquisition in adolescent athletes. Therefore, this study aimed to investigate the longitudinal differences in bone acquisition and bone metabolism between adolescent males participating in osteogenic (football) and non-osteogenic (swimming, cycling) sports compa...

Objective: Little is known about the effects of muscle strength and muscle mass on bone health in children and adolescents. We examined the relative impact of muscle strength and muscle mass on bone mineral density in Japanese adolescents.Methods: Subjects were 236 adolescents aged 15–18 years in August 2010 and August 2013 who were enrolled in the Kitakata Kids Health Study in Japan. Cross-sectional data including appendicular skeletal muscle mass ...

Objective: Over the last decade, there has been increasing scientific interest in vitamin D, and it is now advised that all pregnant women and infants should receive vitamin D supplementation. Despite of this, it is recognized that knowledge of vitamin D in the general public is limited. The internet is now an important source of health care information and analysis of internet search activity rates can provide information on disease epidemiology, health related behaviors and ...
